GOMPEN'SATING nn'nnrnel I Patent-ea May 3,1921.

Application filed June 1, 1920. Serial No. 386,457.

To all whom it may concern 7 Be it known that I, SAMUEL GNAGY, a

citizen of the United States, residing at btrasburg, in the county of Tuscarawas and State of Ohio, have invented a new and useful Compensating Bearing, ofwhich the following is aspecification. i

The present invention relates to bearings,

and more particularly to that type of bearng known as the cone bearing, commonly employed in connection with ball androller bearings.

The primary object of the invention is to provide a cone bearing having means for antomatically adjusting the same longitudinally of the shaft on which thebearing is supported, so that the balls or rollers ass- 3- ciated therewith, will, have a free but true seating on the bearing.

A further object of the invention the.

provision of spring means having connec t1on wlth the bearing proper, the spring means being especially designed to cause a rotation of the bearing, 1 associated therewith, the-rotation of the bearing being sufficient to cause the bearing to move longitudi'nally of its shaft.

With the foregoing and other objects in view which will appear asthe description proceeds, the invention resides inthecombination and arrangement of parts and in details of construction hereinafter'described and clalmed, 1t belng understood that changes in the precise embodiment of the invention herein disclosed, may be made with 1n the scope of what 15 claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a side elevational view of a cone bearing, f'having the adjusting means applied thereto, the balls associated therewith being shown in dotted lines. 3

Fig. 2 illustrates a longitudinal sectional view through a bearing.

Fig. 3 illustrates an end elevational view of the same.

Fig. 4 illustrates a sectional view taken approximately on the line 4 4 ofFi 2.

Referring to the drawing in detail, the

supporting shaft, which maybe employed for supporting wheels or the like, is indicated by the reference character 5,'and provided with the usual threaded extremity, 6 by means of which the usual bearings are that the balls 16 have caused the bearing secured thereon.

Supported on the shaft 5, and cooperating w Contacting with one with thethr'eaded portion 6 thereof, is the mainror supporting nut 7, that is provided j This :nut 7 ,is also provided with exterior threads 10, which threads are preferably formed with a decided pitch to cause the nut 11, which is carried thereby, to; respond freely to the movements of the coiled spring 9, which as shown, has one end thereof dis of the side faces of the nut 11,

From the foregoing it is obvious that the posed in a suitable opening provided in one construction of the coiled spring 9, which encircles the nut 7, 18 such as will-cause a pressureto be exerted on the nut ll, to'cause a sllght rotation thereof, resulting in moving the bearing proper ndicatedby the reference character 12, longitudinally of its shaft t to compensatefor the lost motion. caused by wear.

of the side'faces of the nut 11, is an adjusting washer 13 which is permittedto move longitudinally of the shaft 5, but prevented from rotary movement thereon, by means of the tongue 14, formed integral therewith, and extending inwardly from thewall of the central pening. The tongue 14, in operation, is disposed in the groove 15 formed in one of the sur faces of the shaft 5, and'extending from om:

end thereof, terminating a predetermined vdistance from the end. I

The bearing 12 is of a particular construction, being such as will revolve on the shaft 5, to theend'that the surface on which the balls" 16 operate, is constantly changing, therebydistributingthe wear directed to the bearing 12 through a greater portion of the surface thereof.

In'order that th nut 7 will be maintained in, a stationary position, with relation to the shaft 5, an opening 17 is provided in thenut, which opening-is adapted to register with the opening 18 provided in the shaft the registering opening being designed to accommodate the cotter pin 19. I

From the foregoing it is obvious that the tension of the spring is such as will rotate the nut 11, in the event that the bearing becomes worn. I

In the operation of the device, assuming 12 to wear so that the bearing 12 is no longer properly contacting With the balls 16, it is obvious that the coiled spring 9 which tends to rotate the nut 11, will cause the washer 13 to be moved slightly, to the end that the bearing 12, is also moved to take up the space caused between the bearing and balls 16.

hat is claimed as new is 1. In a compensating bearing, a supporting shaft having a threaded portion, a nut disposed on the threaded portion, and provided with exterior threads, a nut disposed on the threaded portion of the first mentioned nut, a Washer contacting with one of the surfaces of the last mentioned nut, a bearing member associated With the Washer and adapted to be moved longitudinally of the shaft, means for preventing rotary movement of the washer, and means for antomatically rotating the second mentioned nut.

2. In a compensating bearing, a support ing shaft having a threaded portion, a nut operating on the threaded portion, a washer disposed at one end of the nut, a bearing having one of its surfaces contacting with the Washer, a nut operating on the first mentioned nut, and a coiled spring having connection with the nuts, for causing one of th nuts to rotate on the shaft for moving the bearing longitudinally of the shaft.

3. In a conpensating bearing, a suppor ing shaft having a threaded portion, a nut operated on the threaded portion, said nut being provided With exterior threads, an adjusting nut operating on the threaded portion of the first mentioned nut, a Washer on the shaft, and a bearing contacting With the Washer, a coiled spring having one end thereof secured to the first mentioned nut, the opposite end of said spring being secured to the adjusting nut, and said spring adapted to exert a tension on the adjusting nut circumferentially of the shaft.

4:. In a compensating bearing, a supporting shaft having a threaded portion, and having a groove formed in one surface thereof, a nut operating on the threaded portion, a shaft, an adjusting nut carried by the first mentioned nut, a Washer contacting with the adjusting nut, said Washer hav ing a tongue positioned in the groove of the shaft, to prevent rotary movement of the Washer, a bearing member on the shaft and contacting with the Washer, and spring means carried by the nuts to cause the bearing member to move longitudinally of its shaft.

5. In a compensating bearing, a supporting shaft having a threaded portion, a nut supported on the threaded portion, an adjusting nut on the first mentioned nut, a Washer contacting with the adjusting nut, a bearing member disposed on the shaft and adapted to revolve thereon, a coiled spring embracing th first mentioned nut, and having its ends connected to the nuts to cause rotary movement of oneof the nuts, and means for preventing rotary movement of the Washer.

In testimony that I claim the foregoing as my own, I have hereto afiixedjmy signature in the presence of tWo witnesses.
